Memory leak when using Select plugin

shadowen77

I've been trying to track down a nasty memory leak. I'm using the latest version of Datatables in Chrome 54, but I'm using 12,000 rows of data, so any kind of memory leak is bad.

I have narrowed it down to the Select plugin. I've modified an example to create a table with 20,000 rows. I then destroy that table, and take a heap snapshot. My results are:

Before destroy() - 24MB used
After destroy(), select plugin installed - 24MB
After destroy(), no select plugin - 9.5MB

You can profile these two cases yourself:

The code is simple, basically:

    var data = [];
    for ( var i=0 ; i<20000 ; i++ ) {
        data.push( [ i, i, i, i, i ] );
    }

    table = $('#example').DataTable( {
        data:           data,
        deferRender:    true,
        scrollY:        200,
        scrollCollapse: true,
        select: true
    } );

        table.destroy();
        table = null;  

Any ideas? I must be missing something.
